DLL kommunication

Hi The topics to your problem are a.) win32 interoperability or b.) com interoperability. a.) http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncscol/html/csharp09192002.asp The mechanism to use win32 code in a managed (.net framework) environment is called P/Invoke (platform invoke). b.) msdn and google has several arcticles and samples. For both, a.) and b.) is it possible to create MC++ (managed extensions) wrappers. Those encapsulates the unmanaged code with managed code. Simon
